This thread is resolved. Here is a description of the problem and solution.
Problem:
You are trying to add translations to strings in WPML, but encounter an error even after increasing the memory limit, clearing the WPML cache, and updating all plugins. Specifically, when you attempt to add a translation with '0', it fails unless you add a space after the '0'.
Solution:
We recommend the following steps to resolve this issue:
1. Create a full backup of your site.
2. Connect to your site via FTP.
3. Navigate to
wp-content/plugins/wpml-string-translation/classes/string-translation-ui/ajax/SaveTranslation.php
and locate the method
\WPML\ST\Main\Ajax\SaveTranslation::run
.
4. Modify the line from:
if ( $id && $translation && $lang ) {to:
if ( $id && isset($translation) && $lang ) {5. Save the changes and verify if the issue is resolved.
